摘要

The influence of weaning on the activity of trypsin, lipase and carboxyl ester hydrolase (CEH) in pancreatic tissue and small intestinal contents was investigated in 64 piglets. The activity of all enzymes in the pancreatic tissue declined following weaning and reached a minimum on day 5 postweaning. The activity of trypsin in small intestinal contents increased during days 1—9 postweaning, whereas the activity of CEH remained constant and the activity of lipase declined. These results suggest thatthe digestion of fat is of special concern during the immediate postweaning period in piglets due to low lipolytic activity.
